Cyanobacteria /saɪˌænoʊbækˈtɪəriə/, also known as Cyanophyta, are a phylum consisting of free-living bacteria as well as the endosymbiotic plastids which appear sister to Gloeomargarita. They commonly obtain their energy through photosynthesis. They are the only photosynthetic prokaryotes able to produce oxygen. The name cyanobacteria comes from the color of the bacteria (Greek: κυανός, romanized: kyanós, lit. 'blue'). Cyanobacteria, which are prokaryotes, are also called "blue-green algae", though some modern botanists restrict the term algae to eukaryotes. Cyanobacteria appear to have originated in freshwater or a terrestrial environment.

The present invention provides a method for systematically controlling rapid proliferation of cyanobacteria cells in lakes in spring. The method applies physical, biological and chemical methods in an integrated and synergistic manner and includes using flexible enclosures to close a control water area and using modified soil to adsorb and settle algal cells; coupling four technologies including algae control by fish, algae control by biological floating islands, algae inhibition by plants and algae control by microorganisms; and using H₂O₂to kill algae and using 40% FeCl₃+CaCO₃and 50% Ca(NO₃)₂to treat sediment. The method of the present invention has established a complete system for physical, chemical and biological control of algae, forms joint control of exogenous contaminants, endogenous contaminants and cyanobacteria, integrates physical, biological and chemical methods and optimizes systematic methods that are used synergistically.

Bacteria-algae composition for degrading water body and directionally eliminating blue-green algae as well as production process and device

InactiveCN114231454AAchieve directional degradationConsistent growth rateFungiBioreactor/fermenter combinationsBiotechnologyBacillus licheniformis

The invention discloses a bacteria-algae composition for degrading water and directionally eliminating blue-green algae, the bacteria-algae composition comprises the following components in percentage by weight: 80%-85% of compound bacteria, 5%-10% of compound enzyme and 10%-15% of nutrient elements, and the compound bacteria comprise 25%-30% of bacillus licheniformis, 20%-25% of bacillus subtilis, 5%-10% of compound enzyme and 10%-15% of nutrient elements, 17%-28% of lactobacillus plantarum, 13%-20% of rhodopseudomonas palustris and 13%-20% of rhodotorula glutinis; the compound enzyme comprises the following components in percentage by mass: 30% of pectinase, 30% of glucanase and 40% of cellulase. Stable proliferation can be realized under a relatively low dissolved oxygen condition, and the energy consumption required by aeration is reduced. The selected strains are consistent in growth rate and have compound fermentation conditions, so that the production and use cost is reduced. By adding chlorella into the complex microbial inoculant, the proliferation stability and the nitrogen, phosphorus and COD removal capacity of the complex microbial inoculant are improved, the directional degradation effect on cyanobacteria is achieved, and cyanobacterial bloom is inhibited.
